This is a topic where people can discuss there hardest/favourite level in each of the Tomb Raider games. I was actually going to do hardest/easiest level but i knew i would get the same answers:
e.g TR1 - Caves

Also i have decided to do it on the TR3 boards because this is my favourite TR.

Anyway lets start:

Hardest
TR1 - St'Francis Folly That huge drop, all those bats and there is too many "near death experiances" in that level.

TR2 - Temple of Xian Do i need to explain this?

TR3 - Lud's Gate The underwater passage!!

Favourite
TR1 - Atlantis A very fun level.

TR2 - Opera House There is something about this level i just love! I can complete easily in under 5 minutes, without any medipacks.

TR3 - Nevada Desert A beautiful level that can easily be completed.

Those are my views and opinions on the game's levels'.
What are yours?

Hardest:
TR1-Atlantis (enemies were just...)
UB-Atlantean stronghold (I don't know how I completed it the first time; now I try and I can't, it's too hard)
TR2-Opera house (it was too boring, so it was hard + that big guy at the end)
GM-Nightmare in Vegas (stuck at it currently)
TR3-all london levels were difficult
LA-Reunion; cause of the fight, probably
TRLR-Cairo levels (I think you all understand why)
TRC-Red Alert! Those bald men and the bug... :hea:
TRAOD-Boaz Returns (quite difficult boss)
TRL-King Arthur's tomb? (the snake was the only part in this game I had to stop and think some time what to do)

Hardest:
TR1: Natlas Mines (my, I was stuck there for half a year!)
TR2: Floating Islands (or how was it called)
TR3: The final boss level.
TR4: The only TR I never finished, so I can't really tell.
TRC: Red Alert. Don't even remind me of that level.
TR:AOD: Don't really know, the game was quite easy.
TR:L : Nepal, most likely. Don't like to fall. Period.
